Currently the default seccomp profile is fixed. This changes it
so that it varies depending on the Linux capabilities selected with
the --cap-add and --cap-drop options. Without this, if a user adds
privileges, eg to allow ptrace with --cap-add sys_ptrace then still
cannot actually use ptrace as it is still blocked by seccomp, so
they will probably disable seccomp or use --privileged. With this
change the syscalls that are needed for the capability are also
allowed by the seccomp profile based on the selected capabilities.
While this patch makes it easier to do things with for example
cap_sys_admin enabled, as it will now allow creating new namespaces
and use of mount, it still allows less than --cap-add cap_sys_admin
--security-opt seccomp:unconfined would have previously. It is not
recommended that users run containers with cap_sys_admin as this does
give full access to the host machine.
It also cleans up some architecture specific system calls to be
only selected when needed.

This fix tries to address issues raised in #20936 and #22443
where `docker pull` or `docker push` fails because of the
concurrent connection failing.
Currently, the number of maximum concurrent connections is
controlled by `maxDownloadConcurrency` and `maxUploadConcurrency`
which are hardcoded to 3 and 5 respectively. Therefore, in
situations where network connections don't support multiple
downloads/uploads, failures may encounter for `docker push`
or `docker pull`.
This fix tries changes `maxDownloadConcurrency` and
`maxUploadConcurrency` to adjustable by passing
`--max-concurrent-uploads` and `--max-concurrent-downloads` to
`docker daemon` command.
The documentation related to docker daemon has been updated.
Additional test case have been added to cover the changes in this fix.

The jsonlog logger currently allows specifying envs and labels that
should be propagated to the log message, however there has been no way
to read that back.
This adds a new API option to enable inserting these attrs back to the
log reader.
With timestamps, this looks like so:
```
92016-04-08T15:28:09.835913720Z foo=bar,hello=world hello
```
The extra attrs are comma separated before the log message but after
timestamps.
Without timestaps it looks like so:
```
foo=bar,hello=world hello
```

This patch did following:
1) Make filter check logic same as `docker ps ` filters
Right now docker container logic work as following:
when same filter used like below:
-f name=jack -f name=tom
it would get all containers name is jack or tom(it is or logic)
when different filter used like below:
-f name=jack -f id=7d1
it would get all containers name is jack and id contains 7d1(it is and logic)
It would make sense in many user cases, but it did lack of compliate filter cases,
like "I want to get containers name is jack or id=7d1", it could work around use
(get id=7d1 containers' name and get name=jack containers, and then construct the
final containers, they could be done in user side use shell or rest API)
2) Fix one network filter bug which could include duplicate result
when use -f name= -f id=, it would get duplicate results
3) Make id filter same as container id filter, which means match any string.
not use prefix match.
It is for consistent match logic

The documentation already says the cache miss happens only at `ARG`
variable usage, not declaration, but there is a very common implicit
usage: `RUN`, which this commit documents even more, improving on #21790.
Also, use `definition` instead of `declaration`: it's the same thing, and
`definition` is already used in this documentation, contrary to
`declaration`.
Also, distinguish between "instructions" and "variables defined by `ARG`
instructions".

This fix tries to fix the discrepancy between `docker stats` and
`docker run` where `docker run` uses RAMInBytes for all memory
related inputs but `docker stats` uses HumanSize for all memory
related outputs.
To be consistent, `docker stats` needs to use BytesSize for all
memory related outputs to conform to RAMInBytes in `docker run`.
This fix addresses this issue. As BytesSize is used, the test
cases needs to be adjusted to match `KiB/MiB/GiB` instead of
`KB/MB/GB`.
The documentation has also been updated.
This fix fixes#21765.

Once thin pool gets full, bad things can happen. Especially in case of xfs
it is possible that xfs keeps on retrying IO infinitely (for certain kind
of IO) and container hangs.
One way to mitigate the problem is that once thin pool is about to get full,
start failing some of the docker operations like pulling new images or
creation of new containers. That way user will get warning ahead of time
and can try to rectify it by creating more free space in thin pool. This
can be done either by deleting existing images/containers or by adding more
free space to thin pool.
This patch adds a new option dm.min_free_space to devicemapper graph
driver. Say one specifies dm.min_free_space=10%. This means atleast
10% of data and metadata blocks should be free in pool before new device
creation is allowed, otherwise operation will fail.
By default min_free_space is 10%. User can change it by specifying
dm.min_free_space=X% on command line. A value of 0% will disable the
check.

Following #19995 and #17409 this PR enables skipping userns re-mapping

This change implements communication with an external credentials store,
ala git-credential-helper. The client falls back the plain text store,
what we're currently using, if there is no remote store configured.
It shells out to helper program when a credential store is
configured. Those programs can be implemented with any language as long as they
follow the convention to pass arguments and information.
There is an implementation for the OS X keychain in https://github.com/calavera/docker-credential-helpers.
That package also provides basic structure to create other helpers.

There are five options 'debug' 'labels' 'cluster-store' 'cluster-store-opts'
and 'cluster-advertise' that can be reconfigured, configure any of these
options should not affect other options which may have configured in flags.
But this is not true, for example, I start a daemon with -D to enable the
debugging, and after a while, I want reconfigure the 'label', so I add a file
'/etc/docker/daemon.json' with content '"labels":["test"]' and send SIGHUP to daemon
to reconfigure the daemon, it work, but the debugging of the daemon is also diabled.
I don't think this is a expeted behaviour.
This patch also have some minor refactor of reconfiguration of cluster-advertiser.
Enable user to reconfigure cluster-advertiser without cluster-store in config file
since cluster-store could also be already set in flag, and we only want to reconfigure
the cluster-advertiser.
